Test locations in Steel Casting.

[Richard M.]

Hi everyone. I'm currently working on manufacturing a 17-4PH casting (investment casting). But I have doubts about de test specimens from casting because this is a new project for me. The question is: How do I know where to get the test specimens from casting (no separately cast bar)? What orientation, what zones? find attached a image about piece. Could someone help me?

Likewise, how to establish the tension values for machined specimens from casting? There are always values given for separately cast bars but not for specimens cut from casting

Thanks and greetings.

The property requirements are the same, it doesn't matter if they are cut from the casting or separate bars.
How will the castings be heat treated?
What is the variation is wall thickness (min/max)?
What direction are the loads?
